Generative AI with Vertex AI: Prompt Design

GSP1151

Overview

This notebook is covers cover the essential of prompt engineering , include some good practice .

learn more about prompt design in the official documentation .

In this lab, you learn best practices around prompt engineering — how to design prompts to improve the quality of your responses.

This notebook covers the following best practices for prompt engineering:

• Be concise
• Be specific and well – define
• ask one task at a time
• Turn generative tasks into classification tasks
• Improve response quality by including examples

Prerequisites

Before start this lab , you is have should have familiarity with the following concept :

• Basic understanding of Python programming
• general knowledge of how APIs work
• Running Python code in a Jupyter notebook in Vertex AI Workbench

Objectives:

In this lab you will learn how to:

• Get started with prompt engineering with the Vertex AI SDK:
• good practice

How to explore some text generation use cases with the Vertex AI SDK:

• Ideation
• Q&A
• Text classification
• Text extraction
• text summarization

setup and requirement

Before you click the Start Lab button

Read these instructions. Labs are timed and you cannot pause them. The timer, which starts when you click Start Lab, shows how long Google Cloud resources will be made available to you.

This hand – on lab is lets let you do the lab activity yourself in a real cloud environment , not in a simulation or demo environment . It is does does so by give you new , temporary credential that you use to sign in and access Google Cloud for the duration of the lab .

To complete this lab, you need:

• access to a standard internet browser ( Chrome browser recommend ) .

Note: Use an Incognito or private browser window to run this lab. This prevents any conflicts between your personal account and the Student account, which may cause extra charges incurred to your personal account.

• Time to complete the lab—remember, once you start, you cannot pause a lab.

Note: If you already have your own personal Google Cloud account or project, do not use it for this lab to avoid extra charges to your account.

How to start your lab and sign in to the Google Cloud console

1. Click the Start Lab button. If you need to pay for the lab, a pop-up opens for you to select your payment method.
   On the left is the Lab Details panel with the following:

   • The Open Google Cloud console button
   • Time remaining
   • The temporary credentials that you must use for this lab
   • Other information , if need , to step through this lab

2. click open Google Cloud console ( or right – click and select Open Link in Incognito Window if you are run the Chrome browser ) .

   The lab spins up resources, and then opens another tab that shows the Sign in page.

   Tip: Arrange the tabs in separate windows, side-by-side.

   
   Note: If you see the Choose an account dialog, click Use Another Account.
   

3. If necessary, copy the Username below and paste it into the Sign in dialog.

   
   { { { user_0.username | ” Username ” } } }
   

   You can also find the Username in the Lab Details panel.

4. Click Next.

5. Copy the Password below and paste it into the Welcome dialog.

   
   {{{user_0.password | “Password”}}}
   

   You can also find the Password in the Lab Details panel.

6. Click Next.

   
   Important: You must use the credentials the lab provides you. Do not use your Google Cloud account credentials.
   
   
   Note: Using your own Google Cloud account for this lab may incur extra charges.
   

7. Click through the subsequent pages:

   • accept the term and condition .
   • Do not add recovery options or two-factor authentication (because this is a temporary account).
   • Do not sign up for free trials.

After a few moments, the Google Cloud console opens in this tab.

Note: To view a menu with a list of Google Cloud products and services, click the Navigation menu at the top-left.

Task 1. Open the notebook in Vertex AI Workbench

1. In the Google Cloud Console, on the Navigation menu, click Vertex AI > Workbench.

2. Find the instance and click on the Open JupyterLab button .

The JupyterLab interface is open for your Workbench instance will open in a new browser tab .

Task 2. Set up the notebook

1. Click on the file .

2. run through the Prompt engineering good practice section of the notebook .

   • For Project ID, use , and for the Location, use .

Note: you can skip any notebook cells that are noted Colab only.

Classification tasks reduces output variability.

Task 4. Improve Response Quality by Including Examples

Run through the Improve response quality by including examples section of the notebook.

Click Check my progress to verify the objective.

Improve response quality by including examples.

Congratulations!

In this lab you learned prompt engineering best practices using Generative AI with Google Gemini. You explored use cases which follow the best practices of being concise, specific, well-define, providing examples and asking one at a time when using LLMs to generate responses.
